GR61CN3002MR from GR, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VOUT | output | Chip output pin, available as N-channel open-drain or CMOS output per the ordered variant; the absolute maximum output voltage is VSS-0.3 V to VIN+0.3 V. |
| 2 | VSS | power_in | Chip ground pin. |
| 3 | VIN | power_in | Start-up input pin that also supplies the device, with an operating voltage range of 1.5 V to 12 V and an absolute maximum input voltage of 15 V. |
